How you will receive your plants:
Selected by our team of experts and sent from our nursery, you will receive your plant in a pot, ready to plant out.
Can’t plant straight away?
Place the pot in a sheltered spot outdoors and water regularly to keep the soil moist.
Planting tips and hints:
Planting in the ground:
Dig a hole slightly wider than the rootball of the plant. Place the plant in the hole so that it sits at the same level in the ground as it did in the pot. When backfilling, mix in a soil improver such as well-rotted farmyard manure. Firm the soil around the plant and water well.
Planting in containers:
Choose a pot with good drainage holes. Place stones or crocks (bits of broken pottery) at the bottom of the pot to stop the drainage holes clogging up. Use a good quality compost. Feed and water container-grown plants regularly.
When to plant and what to expect at different times of the year
You can plant hardy shrubs, trees and perennials at any time of the year avoiding the two extremes of heat and cold. During the summer months when it is hot and dry the need for watering becomes crucial to aid successful establishment and in the winter when the soil is frozen the plants will not be in active growth either above or below ground and risk getting cold damage. The same is true on the stage or growth you can expect your plants to be delivered in and this will be directly related to the time of year and the season.
When ordering through the year, here’s a summary of what to expect when receiving your plants:
Spring Months: Plants supplied in spring will be starting to show signs of active growth above and below ground.
Summer Months: Plants supplied in the late summer will be more advanced in size and flower stage
Autumn Months: In the autumn plants will be changing colour, showing signs of leaf colour breakdown and be preparing to shut down for winter.
Winter Months: Plants ordered and supplied during the winter months will be dormant and therefore may not be showing growth above the soil level or consist of bare branches with no leaves or bare roots with no soil.
These are all perfectly normal and natural for these types of plants growing in the northern hemisphere. All will still have a very healthy root system that can be planted when the weather is favourable by keeping the new soil level equal to the pot level and therefore not covering the crown of the plant at all. Planting during the autumn and winter months will allow for early establishment in the season and a bigger and better display throughout the main growing season.

How to grow
How To Grow Perennials
Seedlings & Plug Plants Once your seedlings or plug plants have been delivered, remove them immediately from their packaging. Place them in a shallow dish of water for a few minutes to soak the plug of compost. Ideally, these should be potted on immediately or if not, within a day or 2, keeping the plugs indoors in a warm and sunny place and ensuring the compost plug does not dry out. You may need to turn the plugs around as they will start to grow towards the light. Potting on Plugs:
When you are ready to pot the plugs on, lift them by their leaves, not the stem, as these bruise easily and can cause disease to enter and kill the plants. Pot into 9cm pots filled with potting on compost by making a hole big enough for the plug to go into. Plant so the seedling leaves are still proud of the surface. Tap to settle the compost and give them a good water.
Hardening off: Once your potted on plants reach approx 15cm (6in) tall and they are ready to plant out in their final location, the first step is to harden them off before moving them outdoors permanently. This involves simply placing them outdoors during the day and back undercover at night to allow them to get accustomed to the lower temperatures. Once they have been hardened off for a week your plants should be ready to plant out in their final location. Final planting of seedlings & plugs: Once the final frosts have passed, your plugs can now be planted in their final position. Choose decorative patio pots or in the garden borders. Best to use peat free compost or general-purpose compost. Water your compost before planting. Make a hole the size of your pot and plant up to the same level as the original pot. Water again to settle the compost around the root ball.
Bare Root Perennials
Soak the roots in a bucket of cold water for around an hour before planting to help hydrate the plant.
Dig a hole that is deep and wide enough to take the entire root mass. Place the plant in the hole and spread the roots out; the main stem should sit just above the surface of the soil. Fill the hole with soil and firm around the stem of the plant with your hand, or you can use your foot for larger perennials. Give them a good watering.
Garden Ready Plants and larger planting instructions:
Perennials in sizes Garden Ready Plants, 9cm, 1L, and larger, unpack and if the weather is favourable, put outside as soon as it arrives and give it a water.
When ready to plant, ensure it’s positioned in the right location and aspect in the garden.
Keep the area around it clear to avoid overcrowding which reduces its establishment and growth.
Dig a hole approximately twice as deep and 3 times as wide as the plant’s rootball. If your soil is heavy, mix in a soil improver before backfilling. We also recommend adding plant feed into the hole before back filling to help establishment and growth.
Place the plant in the hole so that it sits at the same level in the ground as it did in the pot. Firm the soil around the plant and water thoroughly.
Feeding and aftercare: Keep it well watered and fed for establishment and growth. Can be mulched in autumn/spring each year.
Planting and Flowering Months:
Planting and flowering months are subject to seasonal weather conditions. Recommended planting months for each variety are displayed on each product page. Large perennials over 9cm can be planted for almost all months of the year but take extra care during the cold winter months to avoid frost and hot summer months with extra watering.
